13.9.7 Frequency/direction input
Incremental sensors without direction information
Connect them to FIn_1 only. Let FIn_2 open!
Incremental sensors with direction information
Connect the frequency track (usually track A) to FIn_1.
Connect the direction track (usually track B) to FIn_2.
A positive frequency is displayed, if the direction signal is high at the rising edge of the
frequency signal.
A negative frequency is displayed, if the direction signal is low at the rising edge of the
frequency signal.
